CROSS REFERENCE TO THE RELATED APPLICATIONS

This application is based upon and claims priority to Chinese Patent Application No. 202022945716.2, filed on Dec. 7, 2020, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to the technical field of fitness equipment, and in particular to a boxing speedball.

BACKGROUND

A boxing speedball is a sphere that is used in boxing training after being inflated.

Boxing speedball is a kind of fitness exercise that is simple and easy to learn. Boxing speedballs help people exercise their coordination and improve their reflexes upon long-term practice, and also improves muscle flexibility for the overall body. Moreover, boxing speedballs is great for people to release emotional tension or stress and have fun while exercising.

Existing boxing speedballs are divided into standing boxing speedballs and rope boxing speedballs according to their fixing methods. The standing boxing speedball is fixed to the top of a stand, the bottom of the stand is fastened to a base body, and the height of the boxing speedball is calibrated by adjusting the height of the stand. For the rope boxing speedball, the two ends of the rope boxing speedball are connected to ropes, the ropes are connected to the ground and the ceiling, respectively, and the height of the boxing speedball is calibrated by adjusting the lengths of the ropes at the two ends of the rope boxing speedball. The aforementioned boxing speedballs can achieve the purpose of fitness exercise, but still have the following problems: the aforementioned boxing speedballs are fixed at a single position that cannot be adjusted according to actual needs, which narrows their scope of application. The aforementioned two boxing speedballs occupy much space and thus are not convenient to store. Additionally, the adjustment of the height of these boxing speedballs involves a complicated operation, which is quite inconvenient for the user.

Chinese utility model No. CN210543227U discloses a boxing speedball. As shown in FIG. 10, the boxing speedball includes the ball body 1′, the rebound assembly 2′, the height adjusting assembly 3′, and the connecting assembly 4′ that are successively connected. The connecting assembly 4′ has two connection modes, in which, it can be detachably connected to a horizontal bar or a wall. When connecting assembly 4′ is connected to a horizontal bar or a wall, the ball body 1′ is suspended in the air. Although this utility model can solve the problems existing in the aforementioned two boxing speedballs, the height adjusting assembly and the connecting assembly adopt a threaded connection. When this device is subjected to a force in an opposite direction of the thread, the connection between the height adjusting assembly and the connecting assembly may, consequently, become loose.
